Lecture 5
Lipids nonpolar hydrophobic
carbs polar
Nucleic acids polar phosphate groupst sugar groups
saturated lipids straight singlebonds long saturated low permeability beno extrasp
lowtemp low permeability closertogether so harder to
get thru
flythatlives in artic more unsaturated lipids beneeds to compensate for low perme
Lecture 6
Diffusions
Simple high low
Facilitated down gradient high low concentration
active transport low high uses energy to do so
water moves to higher concentration osmosis t follows solute movement
hypertonic
hypotonic
isotonic 695

andactive site together final product is formed t released
induced fit
allosteric regulation reg molecule binds other than the active site
competitive inhibition req molecule directly blocks the active site
both are reversible
Lecture 8 study
Inside cell
enzymes facilitate chemical reactions
cytoskeleton gives cell shape
microtubules facilitate chromo movement
Between cells
insulin relays a message to cells
Walk pump transports sodium out t potassium into
Hemo carries Oz to cells
Lecture 9
Cell theory all life composed of one or more cells t all arose from other cells
Eukaryotes compartmentalized more efficient
Lecture 11
nucleotides polar has phosphate group nitrogenous base sugar group
DNA Sugar deoxyribose double stranded less reactive
DNA sequence dictates order of aA
5 phosphate
mitosis two diploid daughter cells 46 46
meiosis 4 haploid 23 23 23 23
